Hello! The use of AD9914, using external 50MHz crystal active, but found that fifty-ninth of AD9914 in the process of debugging (REF) pin voltage is very small, only 0.3V, PLL enabled, SYNC_CLK output is 2.06MHz, there should be no realization of frequency doubling function, do not know this where is the problem, hope you can give some guidance.
